Some physical properties of powder materials have great influence on the quality of PVC mixer. For example, the particle size and specific gravity of materials, the roughness of particle surface, the dispersion of powder particles, the agglomeration situation and the composition of particles all affect the mixing effect of PVC mixers.

Generally, the particle size difference is large, for example, the mixing between light and heavy powders will encounter difficulties, resulting in insufficient and uniform mixing, long mixing time, low output and high power consumption; On the contrary, it is possible to achieve efficient mixing in a short time.

The smaller the difference of various physical properties of the powder, the better the mixing effect, and the more difficult it is to separate again after mixing. In order to reduce the re separation after mixing, viscous liquid components can be added near completion to reduce its dispersibility and thus reduce the separation effect. The main factors that affect the mixing effect of the mixer are the selection of equipment and the characteristics of the materials themselves. Therefore, the efficient mixing of powder can be achieved by selecting equipment with high efficiency and high mixing process, and then conducting powder characteristics analysis and pretreatment.
